AWNING WINDOW March 4, 1969 Sheet 3 of2 Filed June 8, 1967 IIVI/E/VTOR AL BRENNER United States Patent Ofiice 3,430,383 Patented Mar. 4, 1969 3,430,383 AWNING WINDOW Al Brenner, 1700 NE. 105th St., Miami Shores, Fla. 33153 Filed June 8, 1967, Ser. No. 644,643 U.S. CI. 49-80 12 Claims Int. Cl. E06b 7/08; E0515 1 7/ ABSTRACT OF THE DISCLOSURE In an awning window having slide bars, vents pivoted to the slide bars at their upper end, interengaging means mounted in the vents and the frame to lock the vents to the frame upon sliding movement of the vents on the 'frame, links pivoted at one end to the slide bars, the other end having a slot and a pin secured thereon adjacent the slot, vent link guides secured to the sides of the vents,

the vent link guides having a pin received by the slot in the link and an elongated inverted S-shape slot receiving the pin of vent links, the S-shape slot having an end portion that is in alignment with the slot when the vents are in their closed position which permits the sliding movement of the vents on the frame and the locking of the vents to the frame by the interengaging means.

This invention relates to awning windows and is an improvement of my U.S. Patents Nos. 2,693,622, 2,905,981 and 3,070,853.

In my patents there are shown and described awning windows which permit the closing of a plurality of vents and be in a closed and weathertight position with relation to the window frame notwithstanding that the vents do not arrive at a closed position simultaneously. The patents show the use of a resilient member in connection with the vent link, which structure permits the sliding movement of the vents after arriving at a closed position. My

Patent No. 2,905,981 utilizes the sliding movement of the bers which have a tendency to lose their resiliency and otherwise fail.

Therefore a principal object of the present invention is to provide awning windows with vent link guides in combination with slotted vent links which permit the vents to swing to a greater open position than the conventional 1 links.

A further object of the present invention is to provide awning windows with vent link guides in which slotted vent links of shorter length than the conventional vent links that are used for the same swinging movement thereof to their open position.

A still further object of the present invention is to provide awning windows with means for first bringing the "vents in contact relation with the window frame to their closed positions and then sliding the vents along the window frame to lock the vents.

With these and other objects in view, the invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawings forming a part of this specification, with the understanding, however, that the invention is not confined to any strict conformity with the showing of the drawings but may be changed or modified so long as such changes or modifications mark no material departure from the salient features of the invention as expressed in the appended claims.

In the drawings:

FIGURE 1 is a perspective view of an awning window constructed in accordance with my invention.

FIGURE 2 is a fragmentary cross sectional view taken along the line 22 of FIGURE 1 with the vents shown in their open positions.

FIGURE 3 is a similar view showing the vents in the partially open position.

FIGURE 4 is a similar view showing the vents in their closed position but unlocked position.

FIGURE 5 is a similar view showing the vents in their locked position.

FIGURE 6 is a side view of the vent link guide.

FIGURE 7 is a fragmentary perspective view of the window frame at the position of the slide bar guide.

Referring to the drawings wherein like numerals are used to designate similar parts throughout the several views, the numeral 10 refers to an awning window in which there are a plurality of vertically swinging vents 11 mounted in a conventional frame F. Although the awning window 10 is shown having three vents 11, any number of vents may be provided as will be readily ascertained upon an understanding of the invention. The frame F is provided with a header 12, a sill 13 at the ends of which are secured the vertical 'jambs 14. Along each of the jambs 14 there is a slide bar 15 slidably mounted thereon by a plurality of combined slide bar guide and vent locks G described in greater detail hereinafter and which are fastened to the vertical jambs 14 by screws 16.

Each of the vents 11 is provided with frames having side walls 20 along which hinge members 21 are secured by screws 22 extending beyond the top edge of the vent frames in a conventional manner. The upper or free ends of the hinge members 21 are pivotally secured to the slide bars 15 by means of pivot pins 23. Secured to each of the side walls 20 of the vents 11 at the position of the lower ends of the hinge members 21 is a vent link guide plate 24 having a pivot pin 25 secured thereon. The pivot pin 25 extends through an elongated slot 26 formed in the end of a vent link 27 whose lower end is pivotally secured to the slide bar 15 by a pivot pin 28. In longitudinal alignment with the elongated slot 26 is a cam follower or pin 29 secured to the vent link 27 and extending into a cam slot S formed in the cam plate or vent link guide 24.

Each of the side walls 20 of the vents 11 are provided with a vent locking pin 17 which engages a flange 18 of the slide bar guide G to lock the vent 11. The vent locking pins 17 are so positioned that when the vents 11 are brought to contact relation with the frame F which is the closed position of the vents 11, the vent locking pin 17 will be positioned slightly below the slide bar guide G and beyond the flange 18 as best shown by FIG- URE 4. Any further closing operation of the vents 11 will serve to slide the pin upwardly and become locked behind the flange 18 as is explained in detail hereinafter.

The slide bars are actuated by the operator 36 as are shown and described in detail in my Patents Nos. 2,693,622 and 2,905,981.

The cam slot S has an approximate reverse S-shape consisting of three connected slotted portions 31, 32 and 33. Slot 31 is an arc of a circle whose radius is equal to the distance between the pins 25 and 29 so that as the vent link swings from the entirely opened position shown by FIGURE 2 to the partially opened position when the cam pin 29 is at the juncture 34 of the slotted portions 31 and 32, the pin 25 remains at the upper portion of the elongated slot 26. The slotted portion 32 is so positioned that its end portion at the juncture 35 is closer to the pivot pin 25 than its other end portion 34 by a distance equal to the movement of the pin 25 in the elongated slot 26. By virtue of this arrangement of parts, as the vent 11 is continued to swing towards its closed position, the vent link 27 swings upwardly and the cam pin 29 follows the slotted portion 32, whereby the pivot pin 25 is made to slide to the lower portion of the elongated slot 26 as shown by FIGURE 3.

With a continued closing of the vent 11 the cam pin 29 will arrive at the end of the slotted portion 32 and is at the top portion of the slotted portion 33 of the cam slot S which is now aligned with the elongated slot 26 of the vent link 27. At this position, the vents 11 have arrived at their closed positions as shown by FIGURE 4. Further actuation of the operator 26 will cause the slide bar 15 to continue to slide upwardly carrying the vents 11. The lock pin 17 will slide upwardly simultaneously with the vents 11 to a position behind the shoulder 18 of the slide guide G to lock the vents 11 in position on the frame F. At the same time the pin 25 will slide up the elongated slot 26 while the cam pin 29 will slide down the slotted portion 33 until the vents 11 will arrive at their aforesaid locked position and the pins 25 and 29 will be found at the upper and lower ends of the slots 26 and 33 respectively.

To open the vents 11, the operator 36 is actuated in a reverse direction to cause the slide bar 15 to slide downwardly carrying the vent 11 downwardly. The pin 25 will slide downwardly as the cam pin 29 will slide upwardly in the slotted portion 33. The lock pin 17 which had been in its locked position behind the shoulder 18 will have slid downwardly free of the shoulder 18 to the position shown by FIGURE 4. A continued operation of the operator 36 will cause the vents 11 to swing outwardly as shown by FIGURE 3 and finally come to the completely open position as shown by FIGURE 2.

From the foregoing it is apparent that there is provided herein a vent link and vent link guide for an awning window which permits the use of a shorter length of vent link for swinging the vent to its completely open position and permitting the locking of the vent to the Window frame after arriving at a closed position.
